The investigation concerns whether comScore and some of its officers
and/or directors have violated Sections 10(b) and 20(a) of the
Securities Exchange Act of 1934.

On November 23, 2016, comScore stated the resignations of the Chairman
of the Company's Board and the Chair of the Board's Nominating and
Governance Committee on November 17, 2016. comScore then stated the
outcome of its internal investigation about "matters related to the
Company's revenue recognition practices, disclosures, internal controls,
corporate culture, and certain employment practices." Afterwards,
comScore's Audit Committee, working with outside counsel and forensic
accountants, determined that "the Company cannot support the prior
accounting for the nonmonetary transactions maintained by the Company
during the years ended December 31, 2013, 2014 and 2015, and
accordingly, revenue and expenses relevant to all nonmonetary
transactions during these periods is being reversed and accounted for at
serious cost rather than at fair value." The Audit Committee furthermore
noted concerns regarding its internal controls. comScore mentioned to
shareholders that "there may be additional accounting adjustments and
such adjustments may be material." When this news was revealed to the
public, comScore stock declined $1.55 per share, or 5.11%, to close at
$28.94 on November 25, 2016, causing shareholders great harm.
